Dear R Users Have run into a problem with the rJava package recently. I do not seem to be able to load the package. I am on R 3.0.2 and updated the rJava package this morning from the Pennsylvania mirrors. I get the following error: ---- package ?mnormt? successfully unpacked and MD5 sums checked package ?rJava? successfully unpacked and MD5 sums checked The downloaded binary packages are in C:\Users\t_uzu_000\AppData\Local\Temp\RtmpOC9zec\downloaded_packages > library(rJava) Error in get(Info[i, 1], envir = env) : cannot allocate memory block of size 2.8 Gb Error: package or namespace load failed for ?rJava? > ---- Any pointers ? Thanks in advance
A small follow-on to this: I uninstalled the package, restarted my
machine, and reinstalled the package. Now, when I try and load the
package, I get an entirely different error message:
> library("rJava")
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object
'C:/Users/t_uzu_000/Documents/R/win-library/3.0/rJava/libs/i386/rJava.dll':
LoadLibrary failure: %1 is not a valid Win32 application.
Error: package or namespace load failed for ?rJava?
Any thoughts appreciated.
Kind regards

You don't really provide enough information like R.Version() but my guess is that you are running 64-bit R either directly or through R Studio but that you have only 32-bit Java installed. I am doing fine on Windows with Java 7 update 45 but had some 64-bit run issues with only Java 7 update 40 64-bit JDK.
